2013 Mercedes-Benz E350 engine problems

Filed Apr 8, 2026 · Engine · TN

Last April, during our routine oil change our mechanic pointed out that our Cam sensors were wicking oil into the harness and making its way to the ECM. This is the first we had ever heard of this issue and the repair was $2400 or so. After researching the problem we wrote to MB USA and never got any response until we filed a lawsuit in sessions court. Turns out we cant do that locally. Mercedes has never contacted us since we registered the car in 2016 and never even acknowledged us until after we filed the attempt to collect the cost of repair. THE problem is endemic and well known. MB put a poorly designed part on their 270 engines and it could have had a worse outcome had the ECM failed while my wife was driving on the interstate Please let me know what has already been done about this problem and if they are required to notify owners. MB is silent on the issue to the point I feel as though they are hiding something.

A Summary of the May 9, 2021, event follows: 6:30 a.m: I Woke up, put on gym clothes and shoes and drove to gym (1 mile from home). 7:01:40 a.m. Turned into the gym parking lot and slowly inched into a parking space. (my Mercedes rides low in the front so I pull in slowly so the block will not scrape my bumper). 7:02:00 a.m. As I pull slowly into the parking space the car stalls and the engine begins revving very loud. I firmly press my right foot (foot was already on the brake as I was inching into the space) on the brake because the car is still making that revving sound. 7:02:15 a.m. The car is at a complete stop for some time. The engine begins revving even louder and surges forward (foot was still on the brake) four feet. The car hits the brick gym building and comes to a standstill. I turn off the engine and sit there stunned. ( A witness signed a statement and said "car was at a complete stop for some time...thought driver would open her door and get out but then the car suddenly surged forward and hit the building"). After getting out of my car and inspecting the wrecked car, I notice the gas cap is open and I shut it. The police show up, and say "no police report" will be made. I have some injuries (concussion, bruises over full torso and legs) but I treat patients with TBIs so self-diagnosed and treated my injuries without seeking additional medical attention. On May 9, 2021, I call CSAA and report the accident. After several conversations with CSAA Claims Advisor Karl Arnold, it appears the car frame is damaged, and repair costs exceed value of car. The building had no damage. I then attempted to access relevant data on the EDR and was misled by the Mercedes Fairfield dealership, Service Unit. I was told by Josh “the data is irretrievable, and you can’t get it”. I asked why would Congress pass the EDR in to law making EDRs mandatory and data belongs to owner, if it is not retrievable? He had no answer. [xxx] PARTS OF THIS DOCUMENT HAVE BEEN REDACTED TO PROTECT PERSONALLY IDENTIFIABLE INFO

Transmission was not shifting properly. The mercedes dealership says that the radiator leaked water into the transmission causing damage to the transmission and possibly the torque converter. Our mercedes only has 44,000 miles on it.

I am reporting a finding on my engine (m276) that is the same related to other mercedes engine models m272 and m273. Recently, I discovered oil in all four (4) engine camshaft solenoid (p/n 276-156-07-90) connectors and the wire harness plug. This is the same problem as described in mercedes benz campaign no. 2012070002, dated september 2012. There should not be any migration of oil beyond the housing of the camshaft solenoid. This is a design defect and the safety concern is that if left uncorrected can cause stoppage of the engine.
